Very nice! I like how the units have really cool historic names and the balancing is cool! I was trying something myself and maybe you could help me out? I would like to either edit trade routes making external trade routes better than internal ones (same perks as internal trade routes plus gold for example) or what i would like even more is creating some kind of international trade unit, being able to have one/serveral per civ you are at peace with! That would make a lot of sense because economy encourages peace. You would have to consider going to war because it could cripple your economics, which makes the rest of the winning options more atractive and would make other civs like cleopatra really attractive ( to play with... i mean as a ruler! :D).
